The Magic of Rocks and Stones-Black Tourmaline
Written and compiled by - Patricia Jean Martin
Even though Tourmaline has been known in the Mediterranean region throughout the ages, it was only in 1703 that it was imported by the Dutch from
Sri Lanka to Western and
Central Europe.
They gave these new gems a Sinhalese name, Turamali, which is thought to mean "stone with mixed colors".
There are many varieties of Tourmaline too many to list here but some are: black (Schorl or Aphrizite), blue (Indicolite), pink and red (Rubellite), brown (Dravite), pink and green ("Watermelon Tourmaline"), green (Verdelite, also known as "Brazilian Emerald"), yellow (Tsilasite, also known as "Peridot of Ceylon"), and the extremely rare colorless (Achroite).
Gem quality Tourmalines are most often members of the Tourmaline group called Elbaite and come from California, Maine, Brazil, Sri Lanka, Pakistan, Tanzania, Kenya, Myanmar and the Malagasy Republic.
In its natural state, all the Tourmalines are characterized by parallel ridges (striations) which run the length of the crystal, as are the Black Tourmalines which are the most common in the Tourmaline group.
Tourmaline forms in igneous and metamorphic rocks and veins.
It frequently occurs with Lepidolite, Microcline, and Spodumene in granite pegmatites and others.
Tourmaline crystals are interesting because they are hemimorphic, having a different shaped top than the bottom of the crystal.
Some crystals of Black Tourmaline can reach a rather large size and can display a great variety of crystal faces.
Another interesting characteristic of this stone is that it is pyroelectric which means that when heated, a positive charge develops at one end and a negative charge at the other.
These charges reverse themselves when the crystal cools.
A piezoelectric charge can be developed if the crystal is compressed (or vibrated) at both ends.
Conversely, if an electrical potential is applied to the crystal, it will vibrate.
Metaphysically speaking, this can help break up an energy blockage, thus bringing new clarity of purpose by helping one integrate and experience the physical and spiritual worlds as one.
Secondly, Tourmalines are pleochroic.
This means that the crystal will look darker in color when viewed down the long axis of the crystal than when viewed from the side.
This property goes beyond the idea that the crystal is just thicker in that direction.
Even crystals of equal dimensions will demonstrate this trait.

Myth & Lore:
Long thin crystals of Black Tourmaline are common as inclusions in Quartz, forming the ornamental stone called "Tourmalinated Quartz".
This stone is unique with its long needle to straw sized, arrow straight, prismatic crystals of pitch black Schorl criss-crossing the clear colorless Quartz.
Alone, Black Tourmaline has long been used by shaman in African, Native American and Aboriginal tribes.
Native Americans used it as a protective stone against negative spells...but when found included in Quartz, it not only breaks the spell, but has been known to energize the "victim" and actually enhance well-being!
Used with Mica, Black Tourmaline is said to be able to return the "spell" or negative energy from whence it came, along with providing a view of the sender of such negativity.
Working like a lightning conductor, Black Tourmaline dispels the negativity and protects against harmful energies such as anger, envy, and greed.
Recognized as the "Teller" stone, all Tourmalines provide insight during times of difficulty or struggle and can aid in "telling" who or what is causing the problem.
Black Tourmaline is well-known and most valued for its grounding effects, as are Obsidian, Hematite, Bloodstone and Smoky Quartz.
However, for grounding of spiritual energies Black Tourmaline is the first stone of choice; a gift of nature which enables its human companion to route and receive higher energies from the Crown Chakra down into the Root Chakra.
